Shielding effectiveness test following the Standard IEEE-299:
  • The Standard IEEE-299 defines the uniform measurement procedures and techniques for determining the effectiveness of electromagnetic shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable to 50 Hz and 100 GHz, respectively) for enclosures having all dimensions greater than or equal to 2 meters.
    The types of enclosures covered include, but are not limited to, single-shield or double-shield structures of various construction, such as bolted demountable, welded, or integral with a building; and made of materials such as steel plate, copper or aluminum sheet, screening, hardware cloth, metal foil, or shielding fabrics.
    EMCTEST Technologies is a leading test laboratory in Italy and Europe for electromagnetic shielding effectiveness testing. Thanks to advanced instrumentation and extensive experience in the field, we perform measurements from 10 kHz to 110 GHz on materials and devices intended for industrial, telecommunications, medical, military, automotive, railway, marine, aerospace, scientific, governmental, and civil applications.

    Typical Test Frequencies

    • Low frequency: 10 kHz, 100 kHz, 500 kHz, 1 MHz
    • Mid frequency: 10 MHz, 30 MHz, 100 MHz, 433 MHz, 700 MHz, 800 MHz, 900 MHz
    • High frequency (RF and microwave): 1 GHz, 1.5 GHz, 2.4 GHz (ISM band), 3 GHz, 5 GHz, 5.8 GHz, 6 GHz, 10 GHz
    • Very high frequency: 17 GHz, 18 GHz, 24 GHz (ISM – Industrial, Scientific, and Medical bands), 26.5 GHz, 30 GHz, 35 GHz, 40 GHz, 50 GHz, 60 GHz (wireless communication and radar applications)
    • Millimeter wave: 75 GHz, 77 GHz (automotive radar systems), 94 GHz, 100 GHz, 110 GHz

    Our test laboratory is equipped to perform shielding effectiveness measurements up to 110 GHz.
